Implementing a TCSC environment
To help the customer maximize the benefits of a thin client environment, HP works closely
with Microsoft, Debian, and Citrix, software leaders in the thin client marketplace. The
following section describes components of a TCSC solution.
The Microsoft component
An HP Windows thin client, running Microsoft Windows CE 5.0 or Microsoft Windows XP
Embedded on the client, supports the latest version of Citrix Presentation Server running in a
Microsoft Windows server environment. In a TCSC environment, Terminal Services running on
Microsoft Windows 2003 Server allow application execution, data processing, and data
storage to occur on the server. Using terminal emulation software, the thin client sends only
display refreshes, keystrokes, and mouse movements to the application server. The server
carries out the specified actions on locally stored data and then returns an updated
display to the thin client (as shown in Figure 2).
This approach promotes centralized application management, minimizing network
bandwidth requirements between application servers and thin clients. With only displays,
keystrokes, and mouse movements as network traffic, communications are minimal and
inherently more secure.
